If you are an Android smartphone or tablet user; and, you use the Google Chrome browser (or the native Android Browser), you may want to take a look at (and install) the mobile version of Web of Trust. I currently use the PC version of Web of Trust on all of my computers to help me determine which sites are reputable and which sites are not.
